Error message during uninstallation

david_at_nb · Postby **david_at_nb** » Wed Apr 16, 2014 8:22 am

I have an installer and everything works fine, except when user tries to uninstall. When he goes to 'Uninstall or change program' and uninstalls my program he receives the following error message.

"Unable to load plug-in library. Please rebuild your project and make sure all required plug-ins are installed. Action skipped."

After pressing ok to this error message boxes, the uninstallation continues without problems.

Any ideas?

Dear David,

does it happen with a specific machine only?

Hi Francisco,

Thanks for the quick reply, I have tested in Windows 7 Premium/professional x86/64, and I always get the same error message.

Dear David,

Did you use any third party plugin with your project?
Did your package work correctly previously?
Did you change anything with your project recently?
Have you re-installed IA?

Did you use any third party plugin with your project?
Besides installing drivers, our software depends only on the .NET framework
Did your package work correctly previously?
This is our first package. Our company decided to go with IA, because of the nice feature to install drivers.
Did you change anything with your project recently?
First/new project. No changes there.
Have you re-installed IA?
We have the express version, however during installation we did not install all the application runtimes (e.g. MsSqlServer, MySqlServe, etc) because it makes the installation process too long and uses to much space in hour HD drivers.

The ones we installed are
Microsoft XML parser 6.0
Microsoft Windows Installer 3.1
Microsoft .Net Framework 2.0,, 3.0, 3.5

I would like to also add that the the type of deployment of our project is of type "Web Deploy". Not sure if there is a relation with the error messages that we are getting

After several testing, finally I was able to uninstall without error messages.

The problem was the driver uninstallation, once I removed the uninstall links for my 2 drivers, everything was fine.

Not sure if this should be considered as a bug. I leave it up to you

.

Thanks.

Dear David,

If I haven't missed anything, I suppose you install/Un-install a driver with your package.

Could you please verify if all the IA plug-ins are effectively installed?

Regards

Dear Francesco,

As mentioned before I did not installed all the IA plugins-runtimes because it makes the process too long and I don't want to install plugins that I will never need (e.g. java, MySQL, SqlServer). After that, I have installed the following plug-ins

(Un)Install MSI Setup
Call DLL Function
Detect MSSQL Instances
DIFX Driver Installation
Download File
.Net Framework (Version 2, Version 3, Version 3.5)
MSXML
Windows Installer

Yes, as mentioned above, I managed to get rid of the messages. But, I had to remove the options to uninstall the drivers.

Thanks for the help
